second to provide a clamping device by which a swinging slidable stra1ghtedge and 4measuring blade having a single longitudinal groove may be attached at either edge to a stock and the ends reversible in every case; third, to provide an adjustable releasable detent to stop the swing of the blade eX- actly at right angles to the face of the stock or allow it to pass to any other desired angle; and fourth, to provide a more positive releasable grip to temporarily retain said blade at any desired angle to said stock. I attain these objects, with others of minor importance, by the mechanism illustrated in the accompanying drawing in which- Figure l is a side elevation of the tool arranged as a level for an under surface, for

instance: a soilit or ceiling, and as a magr'ees'to the opposite or under edge of the stock, in which form the long lower edge of the blade may be used to level a top surface or floor and the face or top edge of the stock 3 to level an under surface or ceiling; Fig. G, isa vertical longitudinal central section of the stock 3 in the 4position shown in Fig. l, all separable parts" removed and the blade 2 indicated by broken lines; Fig. 7, is an under side view of the whole stock in position shown in Fig. l, all separable parts removed Vand the lower edge of the blade indicated by Vbroken lines; Fig. 8, an enlarged sectional udetail view of the detent 34 and adjacent parts, in connection with the oscillating quadrantal limb 24, in the position shown in Fig. t; Fig. 9, a side elevation of the oscillating quadrantal limb and blademlamp, partly in section to disclose the mechanism of the clamp; Fig. 10, a top view of the detent 34 turned to the position shown in Figs. l and 8 to stop the oscillation of the limb and swing of the blade at a predetermined angle to the face of the stock; Fig. 11, an underside view of the detent 34 and its pivotal screw or broad headed journal 36, showing the detent turned to the position shown in Figs. l and 2 to allow the limb 2li to pass through the notch 40; Fig. 12, is a section on the broken line 12-42, of Fig. 9, disclosing the mechanism of the clamping device to lock the oscillating limb and bladeclamp, and showing the blade-seat or bottom of the fork through the blade-clamp; and, Figs. 13, ld, 15 and 16, are diagramsvillustrating respectively the application of the tool in turning a reducing taper, laying out ratchet teeth, gaging the length of a shouldered journal and turning a countersunk head, which are a few of the many ways in which the toolmay be employed.

Similar numerals refer to similar throughout the several views.

The three principal parts of the tool comprise an oblong stock bifurcated at one end and having a longitudinally-grooved working face on one edge and a centering head at the end opposite to said bifurcation, an 0scillatory quadrantal graduated limb and integral blade-clamp pivoted between the ends of the forked branches of the stock and a grooved ruling and measuring blade adapted to slide in and be fastened in said blade-clamp. Other smaller coperative parts are attached and connected as set forth below.

The stock 3 consists substantially of an oblong flat bar one of its edges finished to serve as the working face l; one end has the V-shaped notch or fork formed by the inwardly inclined edges 9 and 9 to form, in conjunction with the seated blade 2, a common centeringsquare as shown in Fig. 1. rIhe face edge has the deep cut groove 46 to loosely but closely receive the blade edgewise as indicated in Fig. 6 and shown in Fics. 1 and 3. The end opposite to the centering notch or head is bifnrcated, divided p arts edgewise and centrally and the ends of the branches bent away from the face edge of the stock to form the supports 4 and 4, through which the pivot or bolt screw 30 is disposed to carry the oscillatory limb 24 and the integral blade-clamp 13. As shown in Figs. 6 and 7 the space between the branches is widened beyond the width of the groove 46 by the curve-edged recesses 6 and 6 on the inside of each branch to receive and let pass the oscillatory limb, thek deeper oblique edged recesses 7 and 7 to receive the inner web-part of the blade-clamp 13 and the still wider curved-edged recesses 8 and 8, to receive the ends of the hub 27 of the integral oscillatory limb and blade-clamp.

The limb and clamp are constructed, disposedA and pivoted as shown in Figs. 1, 2, 4 and 5 and further illustrated by enlarged details in Figs. 9 and 12.

The hub 27 has its bore shaped to form the taper or countersink 28 at one end. The pivotal screw-bolt or journal 30 has the enlarged threaded head 31 seated tightly in one of the branch-supports 4, and the shank 30 passed plainly through the opposite branch-support and is provided beyond with Vthe threaded end 32 to receive the tailnut 33. The shank 30 and the threaded head 31 are connected by the integral countersunk head yor tapered part 29, fitted to exactly lill the countersunk end 28 of' the hub bore. This gives a wedging grip in the hub to lock it against revolving when the tail-nut is turned home. This grip is adjusted and thedesired position of the tailnut when tightened, as shown in Figs. 4'and 5, is attained by turning the screw-head 31.

The blade-clamp 13 is an integral projection from the hub 27 and is bifurcated centrally to receive, seat, and carry the blade 2 edgewise in a plane agreeing with the plane of rotation of the clamp and with the groove 46 in the face of the stock; the blade-seat or bottom of the bifurcation in the clamp and the bottom of the groove 46 in the stock are in alinement on the same tangential line to the hub when the blade is swung to the position shown in Fig. 1 and as indicated in Figs. 6 and 9. The clamp has a central cross-enlargement to form the casing 14 to inclose the clamping bolt 16 axially disposed at the center of and at right angles to the bottom of the fork or blade-seat.A This bolt of larg-er diameter than the width of the bifurcation has the longitudinally reduced portion 17 Fig. 9 lying outside of the bladeseat and space and has at its end the inwardly bent head or lip 18 to engage Vand slide in the groove 23 in the blade. The opposite end of the bolt 16 is threaded to take they thumb-nut 15 by which the inner edge of the blade is drawn and fastened firmly against its seat in the fork. The coil spring 22 is disposed in the annular chamber 21 in the cla-mp or bolt casing to press against the bearing face of the thumb-nut and draw the-bolt with sufcient force to prevent the blade from sliding out when the bolt is loosened. A cross-pin is disposed centrally through the body of the bolt the ends projecting to form the diametrically oppositely disposed radial lugs 20 and 20; and chambers 19 and 19 are formed in the walls of the casing below the blade-seat to receive said lugs. By slackening the nut sufficiently these lugs may be reversed in the chambers by turning the bolt half-way around thus bringing the reduced portion 17 and the hooked head 18 into the opposite branch or side of the fork; whereby the grooved and plain sides of the blade may be reversed and `still retain the same edge of the blade in the seat, or the edges of the blade may be changed'in the clamp without reversing the ends of the blade; thereby allowing the mitered end of the blade within the plane of its movement to be applied in all positions and directions relative to the face of the stock.

The oscillatory quadrantal graduated limb 24 is an integral projection from the hub 27 and disposed oppositely to the bladeclamp, to swing through the forked end of the stock. One side bears along its peripheral edge the quadrantal arc 26 divided into degrees from Zero to 90, and reversely numbered to read readily from either end and give the complemental angles. The opposite side has the graduated arc scale 25 to set the bladev for the exterior angles of different polygons. The stock has on each side two reading or index marks 11 and 12 spaced ninety. degrees apart. The index marks 11 and 11 are placed on the beveled rim of the apertures 5 and 5 in the branches of the stock, through which openings the graduations of the limb are read. And the index marks 12 and 12 are placed on the oppositely beveled sides of the detent table or seat 39 adjacent to the periphery of the limb, all as shown in Figs. 1, 4 and 5. With the blade in the position shown inFig. 4 any degree of angle from Zero to ninety degrees, to the position of the blade shown in Fig. 1, is read at the index mark 12; and, any position of the blade between that shown in F ig, 4 and that shown in Fig. 5, covering ninety degrees or the other half of the semicircle,l is read at the index markll. Y

An adjustable rotatable Ydetent 34 of discal form is mounted on the shank of the screw or broad-headed journal 35, which has its threaded point driven into the detent table or seat 39. The detentV revolves in a plane at right angles to the plane of revolution of the limb; the periphery` of the detent extending into the sweep of oscillation of the limb the edge of which loosely receive the overlapping vedge of the limb and allow .it to swing through unobstructed as indicated in Fig. 11 and shown in Fig. 1. The strikingfand-seat facev of the detent has the annular groove 37 spaced away from the central bore to leave a full length solid hub to support the detentgin this annular groove is seated the coil spring j 3S to bear against the seat and retain the detent against thehead 3G when the screw is turned in or out to adjust the detent to stop the limb to set the blade atthe correct desired or right angle.

to the face edge of the stock, the notch 10 is cut-as shown .in Figs. 2, 5, 6,' and 7,-# to receiveseat and stay the inner -edge of the blade in the position shown in Fig. 5. And on the outside of said arm the boss 44 isdisposed and bored to receive the adjusting screw 43 to limit the inward swing of the blade and stop and seat it parallel with the face of the stock, turned 18() degrees from the position shown in Fig. l.

A spirit level consisting of the ordinary glass tube is disposed in the cylindrical metal case 42 having ears at its ends to receive the screws 45' and 45 by which it is fastened to the back edge of the stock. The stock is recessed away from the open glass face of the level which is turned perinanently toward the stock to avoid breakage. It is obvious that with the range of movement and possible positions of setting the blade this single well protected spirit-level will serve every purpose of leveling plumbing orv laying out any incline from the horizontal to the perpendicular.

The outer end 54 of the blade clamp is squared to the blade-seat and beveled on each side for convenient reading of the graduated scales `on the blade and when placed as shown in Fig. 4 or as indicated in Fig. 15 serves` as a depth gage or to 1 measure a projecting part.
